True or false? The quadratic equation 10p2 - 5p = -8 has one solution.
pav-90 [236]

Answer: False

=============================================

Explanation:

I'll use x in place of p.

The original equation 10x^2-5x = -8 becomes 10x^2-5x+8 = 0 after moving everything to one side.

Compare this to ax^2+bx+c = 0

We have

  • a = 10
  • b = -5
  • c = 8

Plug those three values into the discriminant formula below

d = b^2 - 4ac

d = (-5)^2 - 4(10)(8)

d = 25 - 40*8

d = 25 - 320

d = -295

The discriminant is negative, which means we have no real solutions. If your teacher has covered complex or imaginary numbers, then you would say that the quadratic has 2 complex roots. If your teacher hasn't covered this topic yet, then you'd simply say "no real solutions".

Either way, this quadratic doesn't have exactly one solution. That only occurs when d = 0. Therefore, the original statement is false.

PLEASE HELP ASAP!!!!! please help me!!
Maru [420]

Answer:

Step-by-step explanation:

A)

The parallelogram area formula is  b*h  just like a square but the height is the distance from the base to the parallel top .. not the side length.. that's the only difference.

the base is  x+4

total area is 5x+20

so use those in our formula

area = b*h

5x+20 = x+4 * h   now solve for h   (yes we'll have an x in the other side, but that's okay b/c their formulas do also)

(5x + 20) / (x+4) = h

B)

area = b*h

8x-24 = b*8

(8x-24)/8 = b

8x/8  - 24/8  = b

x -3 = b

C)

area = b * h

12x + 6y = 6 * h

(12x + 6y) / 6 = h

12x/6  + 6y/6  = h

2x + y = h

voila you're don :)

Josephine has a rectangular garden with an area of 2x2
sergeinik [125]

Answer:

Fourth example, (2x - 3) and (x + 2), are possible dimensions

Step-by-step explanation:

Let's go through all the responses one by one;

First of all the area of the rectangular garden can be computed through length times width, such that:

(x^2 - 3) * (2) = 2x^2 + x - 6,

(2x + 3) * (x-2) = 2x^2 + x - 6,

(2x + 2) * (x-3) = 2x^2 + x - 6,

(2x - 3) * (x + 2) = 2x^2 + x - 6

Now in each of these examples, it should be that the products are equivalent to the area according to the length by width rule, so let's see which is truly the correct dimensions by justifying whether the product is truly equivalent to the area.

First example:

2 * (x^2 - 3) = 2x^2 - 6

Now 2x^2 - 6 ≠ 2x^2 + x - 6 so the first example is not a possibility,

Second example:

(2x + 3) * (x-2) = 2x^2- x - 6

Now 2x^2- x - 6 ≠ 2x^2 + x - 6 so the second example is not a possibility,

Third example:

(2x + 2) * (x-3) = 2x^2 - 4x - 6

Now 2x^2 - 4x - 6 ≠ 2x^2 + x - 6 so the third example is not a possibility,

Fourth example:

(2x - 3) * (x + 2) = 2x^2 + x - 6

Here 2x^2 + x - 6 = 2x^2 + x - 6 so the fourth example can act as possible dimensions

Hoochie [10]

Answer:

$9.59 for 7 bags of potatoes

Step-by-step explanation:

First you find the unit rate by dividing 6.85 by 5.

The unit rate should equal $1.37.

Then you multiply that and 7 which equals $9.59
